After the router interfaces shown in the diagram have been configured, it is discovered that hosts
in the Branch LAN cannot access the Internet. Further testing reveals additional connectivity
issues. What will fix this problem?

A.
Change the address of the HQ router LAN interface.

B.
Change the subnet mask of the HQ router LAN interface.

C.
Change the address of the Branch router WAN interface.

D.
Change the address of the HQ router interface to the Internet.

E.
Change the address of the Branch router LAN interface.

F.
Change the subnet mask of the HQ router interface to the Internet.

Explanation:
The serial line connection between the Branch office and the HG office should have interfaces that
belong in the same subnet. Based on the diagram above, the WAN interface of the Branch router
is configured with an IP address that is in a different IP network than the serial interface of the HG
router. As it is set up currently, no traffic will pass from the Branch router to the HG until these two
interfaces are in the same subnet.
